WATERLOO, Iowa (AP) — A man hospitalized after an alleged knife-wielding attack toward Waterloo police officers in May has been arrested in the case.

The Iowa Division of Criminal Investigation says 39-year-old Richard Anderson was taken into custody Monday. He has been charged with one felony count of interference with official acts while displaying a dangerous weapon.

DCI says Anderson advanced toward the officers on May 15 and threatened them with a knife. Anderson is accused of refusing to drop the weapon and demanding that the officers shoot him.

Officers eventually shot Anderson, who received serious injuries and remained hospitalized until his arrest. None of the officers were injured.

Anderson is currently being held on $100,000 bond at the Black Hawk County Jail. Records do not list an attorney.
